During an interview on Thursday, conservative radio host Larry O’Connor of WMAL in Washington told Trump that his callers wanted to see an investigation into the seven-year-old Uranium One deal. Back in 2010, when Clinton was secretary of state, a Russian nuclear energy firm bought a controlling interest in Uranium One. Since then, the deal has become a major talking point in conservative media.

Trump lamented:

“But you know the saddest thing is that because I’m the president of the United States, I am not supposed to be involved with the Justice Department. I’m not supposed to be involved with the FBI. I’m not supposed to be doing the kind of things that I would love to be doing. And I’m very frustrated by it.”
